Use the search sensitivity screen to determine
the size of an AC load needed for the FX to turn
ON and leave SEARCH mode.
• Pressing decreases sensitivity (a
bigger load is needed to turn the FX on)
• Pressing increases the sensitivity
which means a smaller load (less wattage) will
turn the FX on
• Decreasing to zero disables SEARCH mode
Press to view the next SEARCH screen.
The FX produces pulses to detect AC loads. The
search pulse length screen allows adjusting the
number of pulses (from 4 to 20) or cycles to
more reliably detect AC loads. A setting of 8 or
higher, adjusted using and ,
is recommended. Press to open the
search pulse spacing screen.
The search pulse spacing screen adjusts the
amount of time the FX waits before producing
additional AC pulses to sense a load. The higher
the number of cycles, the lower the FX power
consumption, but the longer it takes before the
AC load is powered. The cycles range from 4 to
120 cycles (two seconds). Press to
complete the SEARCH menu.

SEARCH MODE
An FX consumes a small amount of power when it is not actively supplying power to loads or for
battery recharging. During this SEARCH MODE, the FX sends out AC pulses to sense load demands.
Once a large enough load is sensed, the FX turns ON and provides AC power. Using SEARCH mode, a
user can adjust the FX so it only comes ON for certain size loads and not for smaller ones. The SEARCH
features are mainly used in off -grid systems to conserve power.
NOTE: Some loads will require experimenting with the SEARCH settings.
